How do I set my camera to take video? I turn it on and set theburst modeto AVI, but the camera will only take pictures.

Am I doing something wrong?

It did finally take a video, but im not sure why. The video was taken in a low light source and the manual says it will switch to one picture mode if it detects a low light. Ive tried pointing the camera directly at a light and it willonly take pictures. Ive even tried turning all the lights out, with the same results....

I have had the same problem.
I have gotten a few videos, but occationally it's all white out??
Hopefully we can get some suggestions / answers?
